After a period of reproduction in this phase, the gonidia became progressively enlarged to reconstitute the original form. In one species of Spirillum, the cycle was induced by the addition of penicillin to the medium, and in this and certain other respects was reminiscent of the L-cycle., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-14-3-672
